Bug#39008: -o DPkg::Options="--force-overwrite" does not work

[Raphael Hertzog <rhertzog@hrnet.fr>]

Package: apt
Version: 0.3.6

With the latest dpkg that does not force-overwrite by default I wanted
apt to add this tag automatically to the dpkg command line, so I read
the man pages apt-get and apt.conf and tried those commande lines :

~@k6$ sudo apt-get -o DPkg::Options="--force-overwrite" dist-upgrade
~@k6$ sudo apt-get -o DPkg::Options={"--force-overwrite"} dist-upgrade

But none of them worked ... and the confirmation that none of them work is
that :
~@k6$ sudo apt-get -o DPkg::Options={"--force-overwrite"} -o Debug::pkgDPkgPM="true" install jadetex
[...]
/usr/bin/dpkg --force-depends --force-remove-essential --remove tetex-nonfree
/usr/bin/dpkg --unpack /ftp/debian/dists/unstable/main/binary-i386/tex/jadetex_2.6-3.deb
/usr/bin/dpkg --configure jadetex 

The specified tag is not added to the command lines ...
I may be wrong on the syntax of the command line because it's explained
that we must use a list notation (which is not documented) :
       Options
              This is a list of options  to  pass  to  dpkg.  The
              options  must  be specified using the list notation
              and each list item is passed as a  single  arugment
              to dpkg.

If my syntax is wrong then the correct syntax should be
better documented somewhere ...

Thanks for your great work on apt,
